2.2 Heading structureMediumIndustry consensus
Multiple <h1> tags
Several h1s on a page blur which heading is the main one. HTML5 technically allows it, but for clarity I keep one h1 and use h2s below it.
What it is
Several h1s.
Why it matters
Not fatal (HTML5 allows it) but can dilute the primary-topic signal.
How to fix it
Prefer one clear h1.
How to find it on your site
- Crawl or view source and count h1 elements per page.
- Identify templates or components adding extra h1s.
- Demote secondary h1s to the appropriate level.
- Keep a single, top-level h1.
Cross-reference to ranking and citation factors
One clear h1 gives the strongest topical anchor. Multiple h1s dilute that focus.
Impact
Low-medium. Consensus.
